Question
The correlation below is used to calculate the heat transfer coefficients for forced convection
owing to laminar flow outside flat plates.
k0.67 (vp)0.5 co.33
h = 0.644
D0.5µ0.17
Where h is in W/m²-K
v is in m/s
p is in kg/m³
Cp is in J/kg-K
D is in m
µ is in Pa-s
What units must the constant 0.644 have?
What should be the value of the constant when all units are
converted to English units (masses in lbm, lengths in ft, temperatures in oR,
times in h, energies in Btu)?
